ISDN Termination Node IC Cuts Down Cost & Power

The T9000, an ISDN network termination node device, is said to reduce the silicon cost for ISDN equipment by about 30% and to cut power consumption by some 20% compared with competing devices. The system-on-a-chip integrates a microcontroller with ISDN Network Termination Node (NT1) functions and memory and supports two analog phones. It performs the typical NT1 function of 2-to-4-wire conversion on ISDN B channels.The silicon cost reduction helps reduce ISDN and pair-gain equipment costs while the lower power requirements allow service providers to deliver more efficient, remotely powered network termination equipment located at the customer premises. Reduced remote power requirements also help maintain critical emergency communications in the event of local power outages. Samples are delivered from stock.
